  • Publication number: 20230400630
    Abstract: An optical phased array is provided, including: a silicon substrate; a silicon oxide layer; an optical waveguide layer including a coupling beam splitter and a grating antenna; a silicon oxide cladding layer, disposed around the optical waveguide layer and filled in the band-shaped gap; and one or more lithium niobate phase shifters; each lithium niobate phase shifter includes: a lithium niobate thin film located in the band-shaped gap, a lithium niobate optical waveguide disposed over the lithium niobate thin film and connected to the coupling beam splitter and the grating antenna, modulation electrodes. The present disclosure uses materials with high electro-optical coefficient and low loss, such as lithium niobate, to replace thermal modulation resistors and the phase modulation mode based on carrier injection used in optical phased arrays, so that the optical phase modulation with low power consumption, high speed and low waveguide loss can be performed.

  • Publication number: 20210190643
    Abstract: A biological sample processing device includes a containing bottle. A receiving opening is provided and a liquid outlet is provided. The device further includes an upper cover assembly and a lower cover. The upper cover assembly is connected to the upper end of the containing bottle. The lower cover is connected to the lower end of the containing bottle. The upper cover assembly includes an upper cover, a lower seal, a piston and a puncturing element. The upper cover is provided with a through hole, and the lower seal is disposed at a lower end of the through hole. The piston is closely matched with an inner wall of the through hole and can slide along the inner wall to drive the puncturing element to pierce the lower seal. The disclosure provides advantages that the biological sample can be processed by the provided device without opening the upper cover.
